Single-Stage PFC Primary-Side-Regulation Offline
LED Driver with Integrated Power MOSFET
Features
Description
This highly integrated PWM controller with power
.
Cost-Effective Solution without Input Bulk Capacitor
and Feedback Circuitry
MOSFET, FLS3217
/ FLS3247, provides several
features to enhance the performance of low-power
flyback converters. The proprietary topology enables
simplified circuit design for LED lighting applications.
.
.
.
Power-Factor Correction (PFC)
Integrated Power MOSFET
By using the single-stage topology with primary-side
regulation, an LED lighting board can be implemented
with the few external components and minimized cost;
requiring no input bulk capacitor or feedback circuitry.
To implement good power factor and low THD, constant
on-time control is utilized with an external capacitor
connected to COMI.
Accurate Constant-Current (CC) Control
Independent Online Voltage, Output Voltage, and
Magnetizing Inductance Variation

.
Linear Frequency Control for Increased Efficiency
Open / Short-LED Protection
Cycle-by-Cycle Current Limiting
Precise constant-current control regulates accurate
output current versus changes in input voltage and
output voltage. The operating frequency is proportionally
changed by the output voltage to guarantee DCM
operation with higher efficiency and simple design.
Over-Temperature Protection with Auto Restart
Low Startup Current: 20μA
Low Operating Current: 5mA
VDD Over-Voltage Protection (OVP)
VDD Under-Voltage Lockout (UVLO)
FLS3217 and FLS3247 provide protection features such
as open-LED, short-LED, and over-temperature
protection. The current-limit level is automatically
reduced to minimize the output current and protect
external components in short-LED condition.

Functional Description
FLS3217 / FLS3247 is an AC-DC PWM controller for
LED lighting applications. TRUECURRENT® techniques
regulate accurate LED current independent of input
voltage, output voltage, and magnetizing inductance
variations. The linear frequency control in the oscillator
reduces conduction loss and maintains DCM operation
in the wide range of output voltage, which implements
high power factor correction in a single-stage flyback
topology. A variety of protections, such as short/open-
LED protection, over-temperature protection, and cycle-
by-cycle current limitation stabilize system operation
and protect external components.
Power-Factor Controller (PFC) and Total
Harmonic Distortion (THD)
In a conventional boost converter, Boundary Conduction
Mode (BCM) is generally used to keep input current in
phase with input voltage for Power Factor (PF) and
Total Harmonic Distortion (THD). In flyback / buck boost
topology, constant turn-on time and constant frequency I
Discontinuous Conduction Mode (DCM) can implement
high PF and low THD as shown in Figure 16. Constant
turn-on time is maintained by the internal error amplifier
and a large external capacitor (typically over 1µF) at the
COMI pin. Constant frequency and DCM operation is
managed by linear frequency control.
Startup
Powering at startup is slow due to the low feedback-loop
bandwidth in the PFC converter. To increase power
during startup, the internal oscillator counts 12ms to
define Startup Mode. During Startup Mode, turn-on time
is determined by current-mode control with 0.2V voltage
limit. Transconductance becomes 14 times bigger, as
shown in Figure 15. After Startup Mode, turn-on time is
controlled by Voltage Mode, using the COMI voltage. The
error amplifier transconductance is reduced to 85µmho.

DCM should be guaranteed for high power factor in
flyback topology. To maintain DCM in the wide range of
output voltage, frequency is linearly changed by output
voltage in linear frequency control. Output voltage is
detected by auxiliary winding and a resistive divider
connected to the VS pin, as shown in Figure 17.

Figure 15. Startup Sequence
Constant Current Regulation
The output current can be estimated using the peak
drain current and inductor current discharge time
because output current is same as the average of the
diode current in steady state. The peak value of the
drain current is determined by the CS pin and the
inductor discharge time (tDIS) is sensed by tDIS detector.
By using three pieces of information (peak drain current,
inductor discharging time, and operating switching
period); the TRUECURRENT block calculates estimates
the output current. The output of the TRUECURRENT
calculation is compared with an internal precise
reference to generate an error voltage, VCOMI, which
determines the turn-on time in Voltage-Mode control.
With Fairchild’s innovative technique, constant current
output can be precisely controlled.
Figure 17. Linear Frequency Control
When the output voltage decreases, the secondary
diode conduction time is increased and the linear
frequency control lengthens the switching period. This
maintains DCM operation in the wide output voltage
range, as shown in Figure 18. The frequency control
also lowers primary rms current with better power
efficiency in full-load condition.

BCM Control
Open LED Protection
The end of secondary diode conduction time is possibly
over a switching period set by linear frequency control.
In this case, FLS3217 and FLS3247 don’t allow CCM
and the operation mode changes from DCM to BCM.
Therefore, FLS3217 and FLS3247 eliminate sub-
harmonic distortion in CCM.
FLS3217 and FLS3247 protect external components,
such as diode and capacitor, at secondary side in open-
LED condition. During switch-off, the VDD capacitor is
charged up to the auxiliary winding voltage, which is
applied as the reflected output voltage. Because the VDD
voltage has output voltage information, the internal
voltage comparator on the VDD pin can trigger output
over-voltage protection (OVP), as shown in Figure 21.
When at least one LED is open-circuited, output load
impedance becomes very high and the output capacitor
is quickly charged up to VOVP x Ns / Na. Then switching
is shutdown and VDD block goes into “Hiccup Mode” until
the open-LED condition is removed, shown in Figure 22.
Short-LED Protection
In the event of a short LED condition, the switching
MOSFET and secondary diode are usually stressed by
the high-power current. However, FLS3217 and
FLS3247 change OCP level in short-LED condition.
When VS is lower than 0.4V, the OCP level lowers to
0.2V from 0.7V, as shown in Figure 17. Power is limited
and external component current stress is relieved.

limits the primary-side current and VDD “hiccups” up and
down in between UVLO hysteresis.

Over-Temperature Protection (OTP)
The built-in temperature-sensing circuit shuts down
PWM output once the junction temperature exceeds
150°C. While PWM output is off, VDD gradually drops to
the UVLO voltage. Some of the internal circuits are shut
down and VDD gradually increases again. When VDD
reaches 16V, all the internal circuits start operating. If
the junction temperature is still higher than 140°C, the
PWM controller shuts down immediately.
Figure 22. Waveforms at Open-LED Condition
Under-Voltage Lockout (UVLO)
The turn-on and turn-off thresholds are fixed internally at
16V and 7.5V, respectively. During startup, the VDD
capacitor must be charged to 16V through the startup
resistor, so that the FLS32x7 is enabled. The VDD
capacitor supplies VDD until power can be delivered
from the auxiliary winding of the main transformer. VDD
must not drop below 7.5V during startup. The UVLO
hysteresis window ensures that the VDD capacitor is
adequate to supply VDD during startup.
